ftrace: safe traversal of ftrace_hash hlist Hi Steven, I noticed that concurrent instances of ftrace_record_ip() have a race between ftrace_hash list traversal during ftrace_ip_in_hash() (before acquiring ftrace_shutdown_lock) and ftrace_add_hash(). If it's so then this should fix it. Signed-off-by: Abhishek Sagar <sagar.abhishek@gmail.com> Cc: rostedt@goodmis.org Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
